they are located on the top right corner
Beryllium (Be). This is because on the periodic table Be is located in the same group (column) as Calcium and is the highest element in that column. Elements of the same group have similar properties and their masses decrease the higher they are in the group.
The number of nucleons present in an element is equivalent to its mass number.
Elements in the same period (row) have the same number of electron shells or energy levels
All of these elements are located in the third period of the periodic table. Hence, they have the identical valence shell.
they are located on the top right corner
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.
Metals are located on left side in periodic table.Eg-group 1,2 elements
Representive elements
On the left of the periodic table, especially group 1 and group 2 elements.
Elements with similar physical and chemical properties are located in a group.
They all are Halozen elements.
Nonmetals.
Alkali metals are group-1 elements. They are located at extreme left in periodic table.
The elements located in the first column, group IA on the periodic table, are called alkali metals.
Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.
